The BD7692FJ-E2 is an integrated circuit from ROHM which provides power factor correction (PFC) for AC-DC power supplies. It consists of an integrated gate driver, power factor correction controller and common current quota current mode (CCCM) control method. The IC has a power supply range from 85V to 530 V AC and frequencies from 47Hz to 63 Hz. It supports multiple PFC functions and primary side regulation which can reduce the number of components. It also has integrated protection features such as primary current control, voltage loss protection and soft start/stop. The chip is small and low power, making it suitable for applications such as LED lighting systems, household appliances, and computer peripheral systems.
